Assembly in vitro of rhodococcus jostii RHA1 encapsulin and peroxidase DypB to form a nano-compartment [PDF]
, 2013 Rhodococcus jostii RHA1 peroxidase DypB has been recently identified as a bacterial lignin peroxidase. The dypB gene is co-transcribed with a gene encoding an encapsulin protein, shown in Thermotoga maritima to assemble to form a 60-subunit nano ...

Ligninolytic enzymes and its mechanisms for degradation of lignocellulosic waste in environment
Heliyon, 2020 Ligninolytic enzymes play a key role in degradation and detoxification of lignocellulosic waste in environment. The major ligninolytic enzymes are laccase, lignin peroxidase, manganese peroxidase, and versatile peroxidase. The activities of these enzymes

Ligninolysis by a purified lignin peroxidase
Journal of Biological Chemistry, 1993 The lignin peroxidases (LiPs) of white-rot basidiomycetes are generally thought to catalyze the oxidative cleavage of polymeric lignin in vivo. However, direct evidence for such a role has been lacking. In this investigation, 14C- and 13C-labeled synthetic lignins were oxidized with a purified isozyme of Phanerochaete chrysosporium LiP.

Biotechnology Reports, 2017 Degradation of lignin constitutes a key step in processing biomass to become useful monomers but it remains challenging. Compared to fungi, bacteria are much less characterized with respect to their lignin metabolism, although it is reported that many ...

Lignin peroxidase structure and function
Biochemical Society Transactions, 2001 Lignin peroxidase (LiP) plays a central role in the biodegradation of the plant cell wall constituent lignin. LiP is able to oxidize aromatic compounds with redox potentials higher than 1.4 V (NHE) by single electron abstraction, but the exact redox mechanism is still poorly understood. The finding in our laboratory that the Cβ-atom of Trp171 carries a

, 1990 International audienceThe lignin mineralization rate in cultures of Phanerochaete chrysosporium increases with lignin peroxidase concentration up to 20 nkat ml–1. At higher concentrations the rate of lignin mineralization decreases with increasing lignin

Oxidation of a Tetrameric Nonphenolic Lignin Model Compound by Lignin Peroxidase [PDF]
Journal of Biological Chemistry, 2001 The present study maps the active site of lignin peroxidase in respect to substrate size using either fungal or recombinant wild type, as well as mutated, recombinant lignin peroxidases. A nonphenolic tetrameric lignin model was synthesized that contains beta-O-4 linkages.

Effects of ZnO nanoparticles on microbial biomass and enzyme activity in soils containing cellulose and lignin [PDF]
E3S Web of Conferences, 2020 In order to investigate the effect of ZnO nanoparticles (ZnONPs) on soil ecosystem in soil with added cellulose and lignin, five treatments were set up: cellulose, cellulose + ZnONPs, lignin, lignin + ZnONPs, and no addition.
